89Zr-pembrolizumab imaging like a non-invasive way of evaluate clinical reply to PD-1 blockade within cancers.
Waardenburg syndrome (WS) is a genetic disorder resulting in anomalies of derivatives of neural crest cells during development. Patients tend to have variable degrees of pigmentary defects affecting skin, hair, and irides in addition to hearing loss and possible systemic neurological associations. Elevation of the intraocular pressure has been reported in several adult patients with WS. We report the first case of WS to be associated with juvenile open-angle glaucoma in a 20-year-old Egyptian man thus expanding the spectrum of the types of glaucoma that can coexist with the syndrome.
To define tube bleb-pathophysiology, outlining factors that may play a major role in the ultimate success or failure of the bleb. Methods that may be used to advance success of these blebs are discussed.

The study describes the importance of tube shunt bleb pathophysiology, including the role of cytokines, relating to bleb failure or success. Methods to influence these outcomes, are outlined.

Understanding the various parameters involved with the pathophysiology of tube shunt blebs, especially intraocular pressure (IOP), and cytokine content of aqueous. The production of cytokines by tube shunt blebs, and the possible adverse results of this action on a second tube shunt in a different quadrant of the eye.

Tube shunts are conduits transporting aqueous from within the eye to the subconjunctival space. The ultimate end result is to create a drainage bleb over the tube plate. The formation of the bleb is controlled by multifactorial components, including age of the patient, racial background, presurgical IOP, and thereby aqueous cytokine content, and patient's individual reaction to the presence of a foreign body beneath the conjunctiva. Prolonged IOP within the bleb results in cytokine production by the bleb lining. Occluding the tube of a failed implant can prevent damage to a new implant in a different eye quadrant.

Leiomyosarcomas originating from the inferior vena cava are very rare malignant tumors with an extremely poor prognosis. We report FDG PET/CT findings of pathology-proven hepatic metastases from leiomyosarcoma originating from the inferior vena cava in a young woman whose initial presentation was worsening abdominal and chest pain.

Evaluation of utility of cervical ultrasound (US) for detection of thyroid remnants (ThR) in patients after thyroidectomy for differentiated thyroid cancer.

Included were 154 consecutive patients (17-89 years, 123 female and 31 male patients), without known cancer residues or cervical lymph nodes metastases, admitted for ThR ablation with I, 14 to 20 weeks after surgery. Neck uptake of I (Tup) and thyroglobulin were determined, and location and volume of ThR detected by cervical US were recorded. On days 3 to 4 after ablation (1.7-4.6GBq, 46-124.3 mCi I), neck SPECT/CT was performed, and I uptake foci were assigned to one of the regions as described below. The anterior neck was divided into 2 compartments superior and inferior to lower margin of thyroid cartilage, and each compartment was subdivided into middle and lateral regions (in SPECT/CT, posterolateral and anterolateral regions were also marked out). I uptake sites and ThR detected by US, if congruent with SPECT/CT, were counted and analyzed.

In total, 341 I uptake foci were found in 150 patients (97.4%) by SPECT/CT and 213 corresponding ThR in 118 patients (76.6%) by US. Ultrasound detected 30% to 46% of I uptake foci in superior lateral regions, 49% in pyramidal lobe/thyroglossal duct area (both P < 0.05), 74% to 77% in inferior lateral regions, and 22% in isthmus (both P > 0.05). Correlation between ThR volume and Tup was strong (r = 0.79), and that between ThR volume and thyroglobulin was weak (r = 0.24).

Ultrasound is less sensitive than I posttherapy scans for ThR detection in patients after thyroidectomy, especially for remnants located above the lower margin of thyroid cartilage.

Clinical evaluation revealed maculopapular rash, right gluteus cellulitis, and centered retinal hemorrhages. In the intensive care unit, persistent Staphylococcus bacteremia was detected. However, transesophageal echocardiography did not reveal pathologic features. F-FDG PET/CT and cardiac MRI diagnosed a left ventricular infected thrombus, an extremely rare condition especially in patients without structural cardiopathy.
A 58-year-old man with previous melanoma of the left leg underwent whole-body 18F-FDG PET/CT to stage metastatic disease prior to commencing pembrolizumab. Follow-up FDG PET/CT after 3 months of treatment showed partial metabolic response of soft tissue and nodal metastases and diffuse increased thyroid and colonic uptake, suggestive of thyroiditis and colitis. Pembrolizumab was ceased, and a repeat FDG PET/CT scan showed regression of uptake in the thyroid gland and colon, in keeping with resolution of inflammatory change. Immune-related adverse events induced by Immune checkpoint inhibitors, such as pembrolizumab, should be recognized-cessation of treatment often leads to resolution.
